Resumen

Los sistemas digitales han puesto en tela de juicio el rol del microscopio óptico como instrumento insustituible para la enseñanza práctica de la histología. El objetivo de este estudio fue comparar el rendimiento académico y la percepción de los alumnos utilizando microscopía óptica y microscopía virtual en base a una aplicación web, utilizada por primera vez. Se dividieron 92 alumnos de primer año de Odontología en 2 grupos: 1: microscopía óptica, 2: microscopía digital. Todos observaron los mismos preparados de músculo estriado esquelético, estriado cardíaco y liso. Al finalizar, rindieron una evaluación formativa para medir conocimientos y luego se invertieron los grupos. Una vez que todos aprendieron con ambos sistemas se aplicó un test de percepción. Para el análisis de datos se utilizó el Test-t de student, medidas de tendencia central y desviación estandar. En la evaluación cognitiva se obtuvo un promedio de 5,4 en el grupo 1 y 5,7 el grupo 2. Respecto a la percepción, un 73,24 % consideró que la evaluación con microscopia virtual es más justa. La microscopía vitual tiene una mejor percepción por parte de los alumnos y tiende a mejorar el rendimiento académico. Nuevas investigaciones serán necesarias para evaluar esta herramienta de enseñanza.
